What Is Pool Salt?

Are you curious to know what is pool salt? You have come to the right place as I am going to tell you everything about pool salt in a very simple explanation. Without further discussion let’s begin to know what is pool salt?

A sparkling and crystal-clear swimming pool is a source of joy and relaxation for many homeowners. To maintain water quality and ensure a comfortable swimming experience, pool owners often rely on various pool chemicals. One such essential component is pool salt. In this blog, we’ll dive into what pool salt is, how it’s used, and the benefits it brings to pool maintenance.

What Is Pool Salt?

Pool salt, also known as pool-grade salt, is a specific type of salt that is designed for use in swimming pools. It is typically composed of high-purity sodium chloride (NaCl) and is free of additives like iodine or anti-caking agents, which are commonly found in table salt. Pool salt dissolves easily in water and is used to generate chlorine through a process called salt chlorination.

Salt Chlorination: How Does It Work?

Salt chlorination is a method of sanitizing pool water without the need for traditional chlorine tablets or liquid chlorine. Here’s how it works:

  1. Salt Cell Generator: A salt chlorinator, or salt cell generator, is installed in the pool’s circulation system. This device consists of electrodes that use electrolysis to break down the salt molecules in the water.
  2. Chlorine Production: As water flows through the salt cell, the electrical current generated by the device separates the salt into its constituent elements: sodium and chloride. The chlorine gas that is produced is dissolved in the water, effectively chlorinating the pool.
  3. Continuous Chlorination: The process continuously generates chlorine, maintaining a consistent and safe level of sanitation in the pool water. The amount of chlorine produced can be adjusted to meet the pool’s needs.

Benefits Of Using Pool Salt

  1. Consistent Chlorination: Salt chlorination provides a steady and consistent supply of chlorine, reducing the need for manual chlorination and the associated chlorine shocks.
  2. Improved Comfort: Pool salt creates a softer, silkier water feel, enhancing the swimming experience and reducing skin and eye irritation often associated with traditional chlorine.
  3. Reduced Chlorine Odor: Salt chlorination results in water with a milder chlorine smell, making the pool environment more pleasant.
  4. Lower Maintenance: Pool salt reduces the need for frequent chemical adjustments, making pool maintenance more straightforward.
  5. Long-Term Cost Savings: While the initial investment in a salt chlorination system may be higher, it can lead to long-term cost savings due to reduced reliance on traditional chlorine products.
  6. Eco-Friendly: Salt chlorination is considered more environmentally friendly because it reduces the need for handling and storing traditional chlorine chemicals.

Using Pool Salt Safely

While pool salt offers numerous benefits, it’s essential to use it safely:

  1. Correct Salt Levels: Follow manufacturer guidelines for the appropriate salt level in your pool. Adding too much salt can lead to corrosion and equipment damage.
  2. Regular Testing: Periodically test the salt levels to ensure they remain within the recommended range.
  3. Proper Maintenance: Maintain the salt chlorination system as per the manufacturer’s instructions to ensure its continued effectiveness.


Pool salt is a valuable addition to pool maintenance, offering a consistent and comfortable way to chlorinate pool water. Its benefits include improved water quality, lower maintenance requirements, and a more pleasant swimming experience. By adopting salt chlorination, pool owners can enhance their pool environment and enjoy the many advantages it brings to their pool maintenance routine.


What’s The Difference Between Pool Salt And Regular Salt?

It is really just table salt in a different form. The primary difference is that pool salt comes in a larger cuts or sizes. The two chemical elements that comprise pool salt are sodium and chlorine. As pool salt is added to a pool, it dissolves and breaks down into sodium ions and chlorine ions.

What Is The Purpose Of Pool Salt?

Unlike traditional chlorine, saline chlorination keeps pools clean and hygienic without unpleasant chlorine odours, while effectively fighting against bacteria and algae. Salt systems generate chlorine by electrolysis – a process that separates elements from any compound by means of electricity.

Can I Use Regular Salt In My Pool?

Instead, you’ll want to use either refined mineral salts or additive-free food grade (NOT table salt) salts. These contain the levels of sodium chloride you need to achieve the proper chemical reactions for clean, healthy water.

Is A Salt Pool The Same As Chlorine?

Instead of using chlorine tablets or sticks, salt is added directly to the water and a salt chlorine generator (also known as a saltwater chlorinator) converts the salt into chlorine. Like chlorine pools, saltwater pools require a filtration system, although it’s different from a traditional chlorine pool system.
